Sweets Copper Solvent
This is a benchrest must have for shooters. It will very quickly dissolve all copper out of the bore of your rifle. You patch it through and let it sit for NO MORE than 15 minutes. If you leave this in your barrel too long it can be very bad for the inside of the barrel. Definitely recommend this product if you're trying to keep a mirror finish on the inside of your barrel.
Oh sounds like a great product. I've never heard of it and I'm a gunsmith in the US army, so maybe I can introduce to the guys. I always get dirty guns to fix up!!! Thanks for sharing this. Sending you a follow and looking forward to more of your posts. Take care!!
